VAGINAL SYRINGE.

Specification of Letters Patent.

Application filed May 26, 1909.

, atented Dec. 2l, 1909.

sei-iai No. 498,451.

To all whom fit 'may concern:

Be it known that I, VILLIAM HnnsonLAr, a citizen of the United States,'residing at Chicago, in the county of Cook and State of lllinois, have invented new and useful Improvements in Vaginal Syringes, of which the following is a specification.

This invention relates to a vaginal syringe, the object of the invention being to provide a syringe of novel construction for discharging an eifeetive spray and securing a quick return of the douche, and further to provide a syringe which can be quickly, easily and thoroughly cleansed.

The invention consists of the features of construction, combination and arrangement of parts hereinafter' fully described and claimed, reference being had to the accompanying drawings, in which lfigure l is a sectional side elevation of a syringe embodying my invention. Fig. 2 is a front end elevation of the same.

Referring to the drawing, l designates the barrel or stem, 2 the bulb and 3 the nozzle of the syringe, the bulb being preferably made of soft rubber and the barrel and nozzle of hard rubber or other suitable marerial.

The rear end of the bulb is flared, as at. il, and provided at the forward terminal of the llared portion with an annular bead or shoulder 5, and the bulb is formed with an inlet and discharge neck 6 which cncircles .said flared portion and is expanded over said bead, as at (3', thereby detachably securing the bulb to the barrel or stem.

The forward end of the barrel or stem is provided with a reduced nipple 7 which is externally threaded and provided with an annular series of outwardly inclined ports or openings 8. These openings surround a tapered stop lug or' projection 9 having at its extremity a concaved seat 10.

The nozzle 3 is centrally bulged to forma passage of maximum diameter at its center' and thence tapers toward its ends, its inner end being externally threaded to detachably engage the externally threaded nipple. At its outer end the nozzle is formed with an inlet opening 11 and a partially circular inner valve seat l2 and is also formed with an annular series of outwardly and forwardly inclined or tangential discharge ports 13. A ball valve lll, also preferably made of hard rubber, is movable in the nozzle be tween the seats 10 and l2. This valve is of such diameter that when it rests against the seat l0 it will leave a surrounding passage for the free inlet and discharge of the douche through the ports S, and when it rests against the seat l2 will close the opening l1 and leave a surrounding annular passage for discharge of the douche through the ports 13.

The operation is as follows: lVhen the bulb is initially compressed and allowed to expand the contained air is expelled and a partial vacuum is formed in the syringe, which 'auses the valve to move inward against the stop lug 9, as shown in dotted lines in Fig. l., and the douche or solution to enter and lill the barrel and bulb through the ports S and 13 and opening ll. Upon the subsequent compression of the bulb, the douche lirst discharges through the ports S in streams which force the valve lll: against the seat to close the opening ll and, as a consequence, the douche is expelled through the ports l?) .in the form of a spray which will fully penetrate and cleanse the passage and folds of the organ. As the bulb expands the valve again moves inward, as before described, allowing the douche to enter rapidly through thc opening 1l, ports 13 and ports S, so that by the alternate compression and expansion of the bulb the douche will be quickly expelled in a penetrating stream or spray and as quickly returned for the subsequent injection, so that the vagina can be thoroughly irrigated and cleansed within a minimum amount of time and with a minimum amount of labor'.

The advantages of the described construction will thus be apparent, and, as the parts are of simple form and dctachably connected, it will. be understood that the syringe may be readily taken apart for a thorough cleansing when occasion requires.

Having thus described the invention what is claimed as new is A syringe comprising a. barrel having an externally threaded reduced partially closed forward end provided with an annular series of outwardly inclined inlet and discharge ports, and having an integral tapered projection intermediate said ports and formed at its outerl end with a partially spherical valve seat, a bulb upon the rear end of the barrel, a nozzle engaging thc said reduced threaded forward end of the barrel and inclosing said projections and provided with a contracted outer end having a central lilo inlet, an internal partially spherical Valve seat, and a surrounding series of outwardly inclined discharge ports, and a ball Valve 1n said nozzle movable therein between said tapered projection and terminal seat, said Valve being adapted when engaged with said projection t0 permit of the inlet of the douche through the opening and Sets of ports and when in engagement with said terminal seat to close said opening without 10 closing said Surrounding ports.

In testimony whereof I aliX my signature in presence of two witnesses.
